Has Kylie Jenner been joining rapper beau Tyga on tour?

Kylie Jenner has reportedly been joining her new man-friend Tyga on tour in Europe despite both of them arguing that they are not a couple, TMZ reports.

The 17-year-old Keeping Up With The Kardashians star is said to have flown to London Gatwick on Friday before accompanying the rapper to Bordeaux in France and Geneva in Switzerland before travelling on to Athens for Tyga's gig there on Sunday night.

Tyga, 24, has been adamant that the pair are not that serious because Kylie is still considered underage under Californian law – but that's not stopped his ex Blac Chyna from sending out veiled jibes via her Instagram.

Last Thursday – before Kylie left LA for the UK – Blac posted a picture of Tyga kissing her neck, captioning it, "By the way he said I'm not missin no meals" – an obvious reference to Nicki Minaj's Anaconda. She quickly deleted it – but not until hundreds of her fans had liked and commented on the pic.

Tyga and Blac were together for almost three years and have two-year-old son King Cairo together. They were engaged until August this year, when Blac called it off amid rumours that he had cheated on her. Blac is good friends with Kylie's sister Kim Kardashian, who hasn't yet commented publicly on her younger sibling dating Tyga.
